Improvement in water-elevators



NTTn STATES SALMON HEMENWAY, OF FOND DU LAO, VVISOONSIN.

IM PROVEM ENT IN WATER-ELEVATOPLS.

Specification forming part of Letters Patent No. 42,2S9, dated April l2, 1864.

To @ZZ whom t may concern:

Be it known that I, SALMON HEMENWAY, of Fond du Lac, in the county of Fond du Lac and State of Wisconsin, have invented a new and useful Improvement in VVa-ter-Elevators 5 and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. v

My improvement in water-elevators relates to that class in which a windlass and bucket are employed.

Myinvention consists, chiey in an improved construction and arrangement of devices for the purpose of more conveniently discharging the water from the bucket.

In the accompanying drawings, Figure l is a side elevation of awell'curb and windlass with my imprmements attached. Fig. L. is a vertical section of the bucket. Fig. 3 is a detached view of the reel and adjustable flange, the motion of the latter being shown in red lines.

In the drawings, A represents the wellcnrb, the top of which rises so as to cover the the windlass. The reel is supported by a sweep, B, or swinging frame, which is hinged at bottom, so that the top of this frame may swing forward and downward, (carrying the reel, bucket, and water,) until the bucket rests on the bench D, as seen in red lines, ready for discharging the water. The use of this sweep is very convenient, and prevents the necessity of giving the reel M and crank V a backward motion (as ismusual) in lowering the bucket as the latter is brought aside from the well for emptying. The upper board, D, on the front of the curb, is hinged at its lower edge, and connected at its upper edge to the sweep B by means of hooks or bracerods C. By this arrangemement the board folds down with the sweep and serves as a bench for the bucket to rest upon, while the water is discharged. As the bucket is brought to rest on the bench or board D, the further lowering of the sweep renders more rope, when the pressure of the water upon the valve F in the bottom of the bucket moves the rod G and opens the valve, thus letting the water flow out. As the water ows through the valve, it is directed into the pail by means of the spout I on the bottom of the bucket. This combination of valve and spout works' admirably, and will dising the valve while the bucket is rising from y the well and opening the same when the bucket comes to rest. The ange K upon the reel is adjustable in order to shorten or lengthen the reel at pleasure for the purpose of employing more or less rope, according to Y the depth of the well, and at the same time always bringing up the bucket over the center of the well. As the depth of water varies from month to month, or as my reel is applied to different wells, the iiange is adjusted so as to bring the bucket always to the center of the well. The crank V is fitted to the reel shaft by a simple round hole, and fixed thereon by means ot' a set pin, m, which is pivoted at O, and held home by means of a spring, N. By this arrangement itis unnecessary to remove the crank or to let it turn backward in levering the bucket. The pin m being withdrawn by means of lever T, the crank is released, and turns on the shaft. One end of the reel carries a ratchet-wheel, Q, and dog lt. Against the collar of this wheel a brake, I), bears upon the reel-shaft. Both the dog and brake are operated by the lever U, which, upon being brought down, first releases the dog, and then brings the brake to bear upon the reel-shaft. By this action the bucket is readily lowered, and its motion is kept under perfect control of the operator, who keeps one hand upon lever U and the other upon the crank and lever T.

I do not broadly claim the use of `a valve iu the bottom of the bucket, or the placing of the spout upon the bucket itself, but confine myself to the combination and the advantages resulting from such combination.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

The swinging windlass by means of which the bucket is thrown forward and downward, and emptied without the backward motion of the crank and reel, substantially as specified.

In testimony whereof I have hereunto signed my name before two subscribing witnesses.

SALMON HEMENWAY.
